TO ALL lNHOM IT MAY CONCERN:

Be it known that I, C. T..RIDEOU`T, of Boothbay Harbor, in the county pf Lincoln,A and State of Maine, have invented a new and improved Rudder-Gecr; and I do hereby declare that the following is o, full,l clear,

.cndexaet description thereof, which ivill enable those skilled in the art to inekey und use the sbl,refercnce being had to the accompanying drawings, forming part of this specication, in' which- Figure 1 isa decl: plain exhibiting my improved gear.

Figure 2 is a removed section showing the same in elevation.

'-Similcr letters of reference indicate .corresponding parte.

Th nature of this invention consists in the employment of a traversing-segment having teeth,lwhich engage with theteeth of a. disk keyed to the rudder-head, whereby the tiller `can be made shorter, and take up less roo'in iu its travel across the deck, together with e device for securing the rudder in any desired position, as will bc duly described.

In the drawings, A .is the rudder-post, B the rudder. C is an iron sector, huvingo socket, T,- lfor the reception of the tiller T.

This sector is provided with teeth't upon-itslarc, and a strong kolt, b, pivots it to the deck.

Just behind this vsector is the rudder-head A, on which' is keyed a disk, C', of metal, generally of iron or bronce, provided with teeth t', of suitable length 'and pitch to engage, without backlash, the teeth t upon the sector C.l

A. circular' adjunct, D, forms a. part of the disk C', und in'practice is cast upon it.

' This projectionD is provided with a central hole, 7L, und, by the action ofthe rudder, is vibruted over n.

nctollic are D', secured in the deck beneath it.

" though not necessary'.

The hole la, in its cre of vibration, pusses over a series of ho1es,'h Il. z, inthe scidurc D', and can be brought immediately over and to coincide withany one of -the said holes, .as hlt h'", und a strong pintcen be passed down through thehole l1, und into -gmy'ene hole in thearc' D'.

Thus the rudder will be held in a fixed position, and the tiller` T can be unshipped, if desired.

The rudder-head A should extend farienough above the disk C to adlnita tiller shipped orset on in theordinary way, if, by any accident, it should be required.

The rudder, geared as above described, can beoperated with alsimple tiller, or the lutter can be vprovided with the usual wheel-ropes, blocks, und wheel, in connection with it, and in large vessels this would bve desirable,

When at anchor, the rudder can be madeistationury umidships by means of the pin throughthe projection- D und the are D', as before described, und the same moans een be employed to keep the-'rudder hard-a.port or burda-starboard, or at any intermediate point whenoecusion requires.

This simplification 4of the gearing 'attached to ruddcrs renders it unimportant improvement on the other gecring-devices heretofore known and used, all of'such devices being a combination-of three or more-cog-wheels', working on-shufts, and requiring a heavy frame fonsupporting the working parts, which are, from their complication, liable to occident.

These objections my improved gear obviatcs, und while it accomplishes fully the required movement in the rudder, the tillcr traverses on a very short nrc, thus enabling the helmsmon to steer the vessel with case and uniformity. t

Being compact, sim-ple, and strong, it is not liable to get out of-rcpnir, or subject to accident in heavy weather, and can be applied to any Avessel nt a very moderate expense.

I claim usncw, und desiretc secure by Letters Patcnt y The combinatien'and arrangement o i' the toothed sector C, having the tiller und socket T T', `the toothed l diskC, having projection D with hole h, and the perforated crcD, as herein described for the purpose specified.
